Check Contents

Note: This requirement is Not Applicable if the AO has approved users' full access to the Apple App Store for downloading unmanaged (personal) apps and syncing personal data on the device with personal cloud data storage accounts (see Section 2.9 of the STIG Supplemental document for more details). The site must have an AO-signed document showing the AO has assumed the risk for users' full access to the Apple App Store.

Review configuration settings to confirm "Allow My Photo Stream" is disabled.

This check procedure is performed on both the Apple iOS management tool and the Apple iOS device.

Note: If an organization has multiple configuration profiles, the check procedure must be performed on the relevant configuration profiles applicable to the scope of the review.

In the Apple iOS management tool, verify "Allow My Photo Stream" is unchecked.

Alternatively, verify the text "<key>allowPhotoStream</key><false/>" appears in the configuration profile (.mobileconfig file).

On the Apple iOS device:
1. Open the Settings app.
2. Tap "General".
3. Tap "Profiles & Device Management".
4. Tap the Configuration Profile from the Apple iOS management tool containing the restrictions policy.
5. Tap "Restrictions".
6. Verify "Photo Stream not allowed" is listed.

If "Allow Photo Stream" is checked in the Apple iOS management tool, "<key>allowPhotoStream</key> <true/>" appears in the configuration profile, or the restrictions policy on the Apple iOS device from the Apple iOS management tool does not list "Photo Stream not allowed", this is a finding.
